Rumors: Galaxy S IV to have 13MP camera, quad-core A15 CPU

The Samsung Galaxy S IV rumors are heating up - the 4.99" 1080p Super AMOLED screen was brought up again as was the Exynos 5450 chipset rumors (with quad-core Cortex-A15 CPU). The camera has also caught the attention of the rumor mill and apparently it will be a 13MP shooter.
That sounds...

Sure at that pixel density Pentile is no problem, but with others sporting LCDs with RGB at that density, the pressure is on Samsung to show that their Amoled is juat as good.
So practically they don't need RGB, but in the competition, they do.

Heck, 1080p on ~5" is a bit overkill, really, and they could save some batterylife going for lower resolutions, really... But then they might have app compatiblility issues... in this case competition once again is more about sepcs than real life performance (as with most of the megapixel race, even though there are clear excetions of the rule)
